506724-01 Page 5 of 57 Issue 1 108 Installation Locations This furnace is CSA International certified for installation clearances to combustible material as listed on the unit nameplate and in the table in Figure 10. Accessibility and service clearances must take precedence over fire protection clearances.
506724-01 Page 6 of 57 Issue 1 108 • Air filters must be installed in the system and must be maintained during construction. • Air filters must be replaced upon construction completion. • The input rate and temperature rise must be set per the furnace rating plate.
506724-01 Page 7 of 57 Issue 1 108 air is brought into the house for combustion, negative pressure (outside pressure is greater than inside pressure) will build to the point that a down draft can occur in the furnace vent pipe or chimney . As a result, combustion gases enter the living space creating a potentially dangerous situation.
506724-01 Page 8 of 57 Issue 1 108 Air from Outside If air from outside is brought in for combustion and ventilation, the confined space shall be provided with two permanent openings. One opening shall be within 12” (305 mm) of the top of the enclosure and one within 12” (305 mm) of the bottom.
506724-01 Page 9 of 57 Issue 1 108 INST ALLA TION Setting Equipment Up flow Applications The gas furnaces can be installed as shipped in the upflow position. Refer to Figure 10 for clearances. Select a location that allows for the required clearances that are listed on the unit nameplate.
506724-01 Page 10 of 57 Issue 1 108 W ARNING Improper installation of the furnace can result in personal injury or death. Combustion and flue products must never be allowed to enter the return air system or air in the living space. Use sheet met al screws and joint tape to seal return air system to furnace.
506724-01 Page 11 of 57 Issue 1 108 Removing the Bottom Panel Remove the two screws that secure the bottom cap to the furnace. Pivot the bottom cap down to release the bottom panel. Once the bottom p anel has been removed, reinstall the bottom cap. See Figure 13.
